------------------------------------------
Summary: Simplified server-side tests with ServerSideTestRule
Key: SLING-5040
URL: https://issues.apache.org/jira/browse/SLING-5040
Project: Sling
Issue Type: Improvement
Components: Testing
Reporter: Bertrand Delacretaz
Assignee: Bertrand Delacretaz
Priority: Minor
I've been working on prototype at [1] that makes it much easier to create
server-side tests.
See below for an example test using the new {{ServerSideTestRule}} to indicate
that it must run server-side, and the {{OSGiService}} rule to access services
or the {{BundleContext}}. Such a test can be kept alongside other (unit or
integration) tests if that's convenient, and you don't need to build and
install a specific bundle to run it, that all happens behind the scenes.
The {{ServerSideTestRule}} creates a bundle on the fly, with the appropriate
{{Sling-Test-Regexp}} header to make the test available to the existing JUnit
servlet from the junit.core module, installs the bundle, waits for the test to
be available, executes it and removes the bundle.
The server-side test then reports results as usual in an IDE or in a Maven
build. Debugging the test requires setting up a remote debugging session before
executing it, but both can be quickly done from an IDE.
There's a number of things missing, notably a dynamic selection of the test
server as well as embedding of additional required local classes, but for now
this works against a Sling test server launched under {{launchpad/testing}}
with
{code}
mvn clean install -Dlaunchpad.keep.running=true -Dhttp.port=8080 -Ddebug
{code}
after building the latest {{junit.core}} snapshot.
As a next step I'll test this on an actual bundle, using
https://github.com/fizzed/maven-plugins to quickly update the bundle when it's
modified.
Test example:
{code}
public class OsgiServicesTest {
@Rule
public final ServerSideTestRule t = new ServerSideTestRule(getClass());
@Rule
public OSGiService<ConfigurationAdmin> configAdminService =
OSGiService.ofClass(ConfigurationAdmin.class);
@Rule
public OSGiService<BundleContext> bundleContextService =
OSGiService.ofClass(BundleContext.class);
@Test
public void testConfigAdmin() throws Exception {
assertNotNull(
"Expecting ConfigurationAdmin to be injected by Sling test
runner",
configAdminService.get());
final String pid = "TEST_" + getClass().getName() +
System.currentTimeMillis();
assertNotNull("Expecting config " + pid + " to be created",
configAdminService.get().getConfiguration(pid));
}
@Test
public void testBundleContext() throws Exception {
assertTrue(bundleContextService.get().getBundles().length > 1);
}
}
{code}
